SAFETY-ENVELOP.

a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in envelops.

The object of the present invention is to improve the construction of envelops and to provide a simple, practical and inexpensive envelop equipped with a sealing tongue and having concealed interiorly arranged sealing means formed by the terminal portion of the tongue.

A further object of the invention is to provide a safety envelop of this character which will be so constructed that it will be impossible to work the tongue through the envelop and loosen the tongue or slacken the same sufficiently to obtain access to the gummed portion.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Figure l is a front elevation of a safety envelop constructed in accordance with this invention, and shown sealed, Fig. 2 is a rear elevation of the same, Fig. 3 is a vertical sectional view on the line 33 of Fig. 1, Fig. 4 is a longitudinal sectional view on the line 44 of Fig. 2, Fig. 5 is a plan view of the blank from which the envelop is formed, Fig. 6 is a rear elevation of the envelop illustrating the arrangement of the parts before closing and sealing the envelop.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in Which is illustrated the preferred embodiment of the invention, the envelop which is constructed Specification of Letters Patent. Patented Aug, 29, 1916,

or formed from a single blank or piece of paper or other suitable material comprises in its construction a rectangular body portion 1, end flaps 2, tapered outwardly as illustrated in the blank and foldable over the inner face of the body portion and provided with registering longitudinally disposedslots 3 which are adapted to register with a similar slot 4 of an integral top flap 5. The top flap 5 is foldable over the end flap to arrange the said slots 3 and 4 in registering position to receive a tongue 6 of a bottom flap 7 The top flap which is tapered may beof any desiredconfiguration but the bottom flap which carries the said tongue 6 is tapered to form shoulders 8 which are arranged contiguous to the registering slots 3 and 4 when the tongue is in position as hereinafter described whereby the said shoulders will effectively prevent the bottom flap being drawn into the envelop through the slots 3 and 4 and thereby increasing the length of the tongue and permitting the same to be slackened or loosened to afford access to the gummed terminal portion 10 of the said tongue.

In the sealing of the safety envelop the tongue is passed through the registering slots 3 and 4 into the envelop and it extends outwardly through a top slit or slot 11 located at the upper edge or top of the body portion 1 centrally of the said top. The tongue is folded on the lines a and b and it is extended'into a front slit or slot 12 formed in the body portion 1 of the envelop at the upper portion thereof and located below and in spaced relation with the top slit or slot 11. In the sealing of the tongue, the terminal portion 10 is extended upwardly and is pasted or gummed against the inner face of the body portion 1 above the slit or slot 12 between the latter and the top slit or slot. By this arrangement and the provision of the shoulders 8, it will be impossible by bending or bowing the envelop either at the front or back to slacken the tongue and work the front portion so as to loop it at the front slit or slot 12 and thereby afiord access to the gummed or sealed portion. Any bowing or bending of the envelop either toward the front or back will stretch the tongue either at the front or back so that the tongue will be maintained taut under all conditions. Also it will be clear that only av relatively small amount of adhesive material and gummed surface is required for sealing the envelop and that the latter may be easily opened to afiord access to its contents. Also body portion provided adjacent the upper portion with parallel longitudinal slits, end flaps foldable over the rear face of the body portion and provided with registering longitudinal slots, a top flap foldable over the end flap and having a slot extending longitudinally of the envelop and registering with the said slots and a bottom flap provided with an integral sealing tongue extending through the registering slots into the en- Oopies of this patent may be obtained for velop and passing out of the same at the top thereof through the top slit and then downwardly at the front face of the body portion and inwardly and upwardly through the front slit, the terminal of the tongue be ing provided with adhesive material to enable it to be pasted to the inner face of the body portion between the slits thereof, said bottom flap being provided at its juncture with the tongue with shoulders located at the said registering slots and adapted to engage the end walls thereof to prevent the tongue from being drawn farther into the envelop, substantially as and for the purpose described.

In testimony Whereof I afiix my signature in presence of two Witnesses.
